I know this thread is a year old, but I know plenty of folks will be helped by it, as I was. 1994 xj, 40.l, aw4, 4x4.
exhaust manifold cracked between 2 pipes in collector.
seafoam treatment showed me where the leak was with smoke and a white residue.. that settled the "where the hell is all that noise coming from?" question.
Got the replacement manifold with the accordian flex joints from NAPA, and a new driver side motor mount as it was toast. I was disappointed that the manifold had Made in China stamped on it.
As careful as I was, I snapped that darn rear manifold stud at the end of my torque sequence... way less that the 23 lbs set on the wrench! (much swearing, packed the tools, closed the hood and starting my search for manifold bolts and head bolts, as the head needs to come off when that rear stud snaps off inside the head).
Came here, got Summit Racing suggestion... ordered 2 sets, will be tackling the 2.5 YJ next. 1994 yj, 2.5L, ax15
Summit had the 4.0L manifold bolts listed but not the head bolts.
Summit requires you to register.. I did, but still couldn't purchase online, so I called them and ordered. <http://www.summitracing.com/parts/RNB-03408/>
Summit part # RNB-03408
Ordered 2/14/2012 online. I'm on Oahu in Hawaii. USPS tracking says they're on the mail truck and I'll have them this afternoon, 2/18/2012.
So I ended up at headbolts.com Dave Crosby, Nashua NH
These guys are so right on! They will now also have the manifold stud, nut and bolt kit in stock for us next week! Yeah Dave and Ohana!!!! Mahalo
Headbolts.com part #: chbs-1128

Ordered late Sunday 2/13/2012, they were shipped Monday 2/14/2012.
write them at
[email protected] they write right back. =)
They were delivered here in Hawaii Thursday 2/16/2012..
My local Napa, CarQuest and O'reilly stores can't even get them and these folks ( and the US Postal Service ) got them to me in the middle of the freaking Pacific Ocean in 4 DAYS!
When I hear those bought off politicians and media wonks say the USA can't do things right, experiencing the reality of the capability and extreme customer service of US small business and our dedicated Post Office employees that can do this, just shows them up as the greedy liars they are.
Best of luck to all of you, and thank you for posting your projects with pictures and problems you encountered. You've helped us more than you know. One more beer and I start tearing it all apart again, to reinstall with all new studs and bolts after Joe at the Precision Motors machine shop in Kailua gets through with the head.
Big alohas and mahalos,
Mike
